Coghead, a Redwood City, Ca. start-up that lets tech-savvy people create applications from an online service with visually simple forms, a database, and business logic, has raised $8 million in a second round of venture backing.

Here is its statement.

Coghead launched a test version of its offering in Oct., and says it has attracted more than 16,000 developers who are creating customized web-based applications for a wide variety of needs, “from managing sales pipelines to tracking donations to churches.”

It said the service will be generally available in the first half of 2007.

American Capital Strategies (Nasdaq: ACAS) led the round, with participation from SAP Ventures, a division of SAP AG, and existing investor El Dorado Ventures.
